Ho qhibiliha/karabelo ea eona ea exothermic (ΔH = -44.51 kJ/mol) ho baka ho phahama ha mocheso, ho sitisa ho lekana (mohlala, ho fetola motsoako oa alkoxide ho ea ho hydrolysis) le ho etsa hore li-solvent tse belang ka tlase li be mouoane joalo ka ethanol. Ho feto-fetoha ha pH ho itšetlehileng ka mahloriso ho boetse ho beha likotsi likotsing: >1.0 M NaOH e khothalletsa liketso tsa Cannizzaro ho Claisen-Schmidt condensations, ha <2.5 M e fokotsa carboxylation ea Kolbe-Schmitt.

Ho phaella moo, NaOH e monya CO₂/mongobo ho etsa Na₂CO₃ e silafatsang, mme tlhokomelo ya nako ya sebele e sitiswa ke titration e liehang kapa foil ya pH meter ka hara dintho tse phelang. NaOH e tebileng (≥10 M) e senya di-reactor hape, e leng se eketsang mathata a taolo.
